Metallogeny of Chile
Tres Valles is located in the
prolific Cretaceous belt of Chile, which
hosts a large amount of
deposits, ranging from small to
world-class
This belt hosts a variety of deposit
types, including the IOCG (e.g
Candelaria, 700 Mt @ 0.7%Cu) and the stratabound Cu-Ag
“mantos” (e.g El Soldado, 200Mt @
1.0%Cu)
Tres Valles
CRETACEOUS DEPOSITS
3
Stratabound deposits- Jurassic or Early Cretaceous age in Chile, hosted in volcanics/volcanoclastics, subvolcanics
or sedimentary rocks- Developed in the intracontinental back-arc basins (rift zones)- Epigenetic (hydrothermal or LG metamorphic origins are suggested) - Albite is the most common alteration- Mainly stratiform (“manto-type”) but can be lens, breccia pipe, vein or irregular shape,
sometimes present in the same deposit- Main controls are lithologic (permeable strata) and/or structural (extensional faults) or
intrusion-related- Main ore minerals are Chalcocite, Bornite and Chalcopyrite and associated oxides.
Supergenic enrichment is not common (Py poor)

Drilling History
• Vale´s strategy in 2005 was focused on product & geography diversification
• In Chile, the goal was to start an operation in a maximum term of 5 years
• The Project implementation was approved at the beginning of 2008, and no
further exploration has been carried out since then
• After 11 years, exploration will restart at Tres Valles in 2019 11
Drilling and Exploration Strategy
Three stages of drilling in parallel,
aiming to constantly feed the project
pipeline and ensure an extended LOM

Expansion Potential at Papomono-Sur
• PPM Sur zone was discovered at the end of 2011 and only one campaign was performed in 2012, with a single base-line of fan-drillings
• All the sections present open manto-type mineralization (average 1.1% Cu) to the East and some to the West.
• Target: reach 400m along dip, same as Mantos Conexión
14
Ladera Sur Target
Ladera Sur is a 1 km-longexposure of favorable strata(lapilli/ash tuffs and andesites) with several outcrops ofmanto-type Cu mineralization
15
Other Examples of Expansion Potential
CUMBRE is a diorite-grabro plug with 230m-diameter exploited by open pit in 2011-2012. The mineralization was disseminated CC and oxides at surface which gradates to cc-bo downward. Drill-holes cut intervals of disseminated mineralization >100m (Ex: DH-102: 379m @ 0,5%Cu and DH-206: 111m @ 0,9%Cu
Planned Drill-holes
Mineralization is open to depth
20
0m
DON GABRIEL VEINS: besides the great amount of mineralized material to be upgraded through in-fill drilling, the veins are open to NW, with last section presenting high-grade intersections (e.g., 10m @ 2.33%Cu)
IP Anomaly
16
Additional Mineralized Material Around Deposits
• There is an important amount of mineralized material that was not included in the 2018 resource statement due to insufficient drilling
• Some of them are already being exploited via third-party leasing (e.g. La Verde and La Amarilla)
• Most of this material can be upgraded to mineral resources with additional drilling

District Exploration Potential
• More than 100 Cu occurrences have been mapped in the mining properties
• Different styles of mineralization have been found in the tenements block to date, with characteristics of Mantos, veins, skarns, IOCG and intrusive-hosted mineralization
• 70 artisanal exploitation points have been registered. Some of them have geological characteristics similar to what we saw at the Papomono and Don Gabriel orebodies when they were first mapped in 2005
• Historically, similar mining districts have expanded their reserves several times over due to the tendency of manto-type deposits to cluster (up to tens of small-to-medium size orebodies)
Main Occurrences Types
18
Artisanal Mining as an Exploration Tool• MTV takes advantage of the intense artisanal mining activity
in the district as privileged exposures of mineralized zones can be observed
• Detailed mapping and sampling of artisanal mines, together with traditional prospection methods, is a key tool for the targets’ geological interpretation and ranking
• Cumbre and Don Gabriel orebodies were drilled based on preliminary modeling from small pits mapping
19
Manto-type Prospects
• Most of the known manto-type occurrences at Tres Valles are located in the uppermost 200m of Q.Marquesa Fm, under the contact with Viñita Fm (generally between 1300 and 1500 m.a.s.l.), which is a regional redox zone (chemical trap for Cu precipitation)
• Reduced lenses inside Viñita Fm are also mantos host-rocks
• Targets are sets of mantos with tens of meter-thick and strikes > 300m.

Vein Occurrences and Main Exploration Targets
Anomaly identified 400 m south of Condor Vein
• In several parts of the district, there are sets of 100 to 600 m veins that are aligned in more than 1 km long trends
• Grades in veins are typically higher than 1.5 % Cu
• Besides the vein-type potential, mantoscan be also found at depth, as these structures worked as plumbing systems for hydrothermal fluids

Conceptual Target: Cu-PorphyryA hypothetical porphyry system is suggested based on the following characteristics:
- Presence of a wide (2 x 1 km) zone of Quartz-Sericite-Pyrite under the stratabound Papomono deposit, similar to phylliczones of porphyries
- Presence of a high-intermediate sulphidation epithermal vein containing alunite, dickite, enargite, tenantite and pyrite in the NE part of the deposit. This assemblage is not found in any other part of the Papomono deposit and is characteristic of the upper part of porphyry systems
